[PATCH 0/2] coresight: Allow guests to be traced when FEAT_TRF and VHE are present

[James Clark]

The first commit moves the register to sysreg because I add the EL12
version in the second commit. I couldn't really think of the best way
to make it fit in sysreg without any changes, because all the fields are
shared between EL1 and EL2 except for the CX bit which was named
differently for that reason in the original definition. The CX bit only
exists in TRFCR_EL2.

The test results have some single spurious EL2 addresses, but I don't
think this is an issue with this patchset because it happens in the
host-userspace case which maintains the existing programming of
TRFCR. It's likely an issue with the model but I will follow it up
separately.
